What happens if a number is visible on the display?
This is a message code. The numbers are displayed if a successful measurement could not be performed. The user can correct the measuring situation to achieve a measurement. Below you can find the spread sheet from the manual with the corrections:

No.

Cause

Correction

204

Calculation error

Perform measurement again.

252

Temperature too high

Let device cool down.

253

Temperature too low

Warm device up.

255

Received signal too weak, measuring time too long

Change target surface (e.g. white paper).

256

Received signal too high

Change target surface (e.g. white paper).

257

Too much background light

Shadow target area.

258

Measurement outside of measuring range

Correct range.

260

Laser beam interrupted

Repeat measurement.

How to switch off/on the beep?
The beep can be switched off (and on) with a long press simultaneously on minus key and reference key.

How can I activate the keypad lock?
To activate the keypad lock, press CLEAR/OFF key and minus key simultaneously for 2 sec.

How can I deactivate the keypad lock?
To deactivate the keypad lock press the ON/DIST key and afterwards (within 2 Sec.) the MINUS key. Now the keypad lock is deactivated and the device is switched on.

How to switch off/on the display illumination?
The illumination can be switched off (and on) with a long press simultaneously on plus key and reference key.

What exactly is the painter function and how does it work?
The painter function calculates the sum of several individual wall surfaces with a common height. Press func key 1x to go to the area function.
Press plus- or minus key and measure the first wall length, press plus- or minus key again and measure the next wall length. The distance is automatically calculated. Repeat the procedure, until you have measured all wall lengths.
2nd measurement: Measure the wall height.
The result displays automatically the wall areas, which you have selected.

Which formula stands behind the indirect measuring function Pythagoras?
In any rectangular triangle, the theorem of Pythagoras is valid: a²+b²=c². This means the other way round: c=radical of (a²+b²) or b=radical of (c²-a²). One side of the triangle can be calculated, if the other two sides are known. Therefore it is important that the DISTO™ measuring points are at the same level and that measurement 2 is rectangular. With a long press on the DIST-key the minimum function can be activated to get the shortest distance for measurement 2.

Can I use the DISTO™ E7300 (D210) with rechargeable batteries?
Yes, it is possible to use with standard rechargeable batteries. The more powerful the charger system is, the longer you can measure with the Leica DISTO™. We offer a powerful charger system, which is ideal to use with DISTO™: Leica charger UC20 with 2 Micro AAA NiMH batteries, For more information, please check our accessories.

What accessories are recommended?
For measuring of long distances we recommend to use our Leica target plates. If the laser dot is not visible, we recommend you to wear laser glasses (GLB30).

How can I get an extra year’s warranty?
Our standard warranty of 2 years can be extended by one additional year if you register your device here within eight weeks of the purchase date. If the product is not registered, a two year warranty applies.

What does ISO 16331-1 tested mean?
When products and services meet our expectations, we tend to take this for granted and be unaware of the role of standards. However, when standards are absent, we soon notice. We soon care when products turn out to be of poor quality or are unreliable or dangerous. An ISO Standard ensures consistent quality and reliability for a product.

The range and accuracy of laser distance meters depend greatly on lighting conditions and the reflective properties of the target object. For Leica Geosystems it is important that the performance of the device is maintained not only in the test laboratory but even more so on everyday site tasks. Therefore we have worked with external experts to develop a global standard to test and specify laser distance meters and allow comparisons between devices of different manufacturers. Instruments tested in accordance with ISO 16331-1 achieve their promises. Further information can be found here on our website.
